摘　　要：[目的]基于16S rRNA基因序列探讨蜘蛛几个重要类群系统发生关系。[方法]采用贝叶斯法、最大简约法、最大似然法对蜘蛛目(Araneae)6科2亚科蜘蛛的16S rRNA基因序列进行系统发育分析。[结果]隙蛛亚科Coelotinae是漏斗蛛科Agelenidae的一个亚科,隙蛛亚科+漏斗蛛亚科是暗蛛亚科的姐妹群;红螯蛛属Cheiracanthium与管巢蛛属Clubiona之间的关系远于管巢蛛属与近管蛛科Anyphaenidae之间的关系。[结论]16S rRNA基因系统发生结果证实了隙蛛亚科和红螯蛛属的分类地位。[Objective] The research aimed to discuss the phylogenetic relation of some important spider groups based on 16S rRNA gene sequence.[Method] The Bayesian method,Maximum Parsimony and Maximum Likelihood analysis were used to analyze phylogenetic relationship of six families and two subfamilies（Araneae） spiders partial 16S rRNA gene sequences.[Result] The results showed that the Coelotinae is a subfamily of the Agelenidae,and the Coelotinae ＋ Agelenidae are the sister group of the Amaurobiinae.At the same time,the results also proved that the relationship of genera of Clubiona and Cheiracanthium is farther than the relationship of the genera of Clubiona and the family of Anyphaenidae.[Conclusion] The phylogenetic positions of Coelotinae and Cheiracanthium were defined by the phylogenetic analysis based on 16S rRNA gene.
